I'm a mix of both.
I use both. The determining factor is usually the story - whether I need to be able to tell the reader about things that are happening that are not in the view of the protagonist or first person, or do I want the reader to wonder about those things.
I write in first person.
I like writing in first more since most of my writings tend to come out of experiences whether heard or lived off.
I do write both first and third person but I think I have a slight preference for first.
Third person. It gives more freedom to criticize and even make fun of the protagonist.
It depends. Anything can work, provided it's done well. Charlie Stross has two books written in second person, and it works. So there's no single answer to that.
That'a tough question for me because I write both ways. I think it depends on how deeply you connect with a character as to how much you like writing in first or third person.
I find that first person makes it more relatable to the reader, they can place themselves in the place of the characters that speak to them the most.
The majority of my current writing is autobiographical, so I guess its in the first person.
Third person generally, but if a first-person narrative is compelling, it can be very effective.
most of the time first person but somtimes there are exceptions
Honestly, whichever "person" fits the story. I enjoy reading and writing from both first or third person.
Third person is more mysterious. I find a way of flitting between the two is most successful, it gives a sense of intimacy to the reader.
Absolutely first person, as a mother, businessperson, advocate of the disabled, I believe I have a unique voice but can relate my story in a way that everyone can understand.
